I checked with a Dewalt service company and they said that at least in the Dewalt line of tools you could not make any changes like that without changing the switch and possibly the motor as well since they are set up for a particular voltage. You might want to do some more research, like it looks like you have done, to make sure that you do not ruin a good tool. Good luck!
Testimonial: "I gave up on Dewalt because they placed the protection circuits in the tool rather than the battery. Makita still has the circuits in the battery. I don't think voltage is a problem."

I plan to take the bottom end of a Dewalt 20V lithium drill and mate it with a black and decker 18v battery case so all my 18v black and decker tools will work with dewalt 20v lithium batteries. Note that dewalt offers a 4.0 amp version of their battery. Anyone see any problem doing this?
I've found that the Dewalt 20v batteries do not have any undervoltage protection circuit so the adapter would need a circuit from a dewalt drill. Black and Decker 20v batteries do have undervoltage protection but they don't offer any high capacity battery packs (darn!).
It appears the Makita 18v lithium battery has the voltage protection circuits. In addition, there are non-OEM (cheaper) versions of the battery up to 4.0 AH. The parts of a drill to make a socket from are cheap too. Will try making an adapter to fit the Makita battery to all my B&D tools. Note that there is a company that markets a 'universal' battery with adapters but there are no B&D adapters availible yet.
As far as I know the 18Volt batteries is the same thing with the 20V MAX batteries. What does 20V MAX means? 20V Max means that the 18V battery when it is charged fully you will observe that its voltage is 20Volt. That is the reason why in Europe the 20V Max tools are simply 18V tools...
